PHILADELPHIA (973espn.com) - The Eagles still have some time before on-field work begins but it was at least a bit of a surprise that Carson Wentz showed up Monday for the start of the team's offseason program and would not commit to saying the stress fracture in his back which derailed his 2018 season back in December was fully healed.

“It’s still getting there,” Wentz told reporters as Phase I of Philadelphia's OTAs kicked off. “Some of the stuff just takes time. That’s not really the main concern, it’s just kind of how I feel and I feel really good with where I’m at.”

The original estimate, although always a bit foggy, had Wentz, 26, needing about three months to convalesce once he was diagnosed in December, a number long since past.

Wentz's goal remains the start of that on-field work, which is still five weeks away on May 21, a date that will be five-plus months from the injury being identified. If he isn't on the field by then, it would be fair to raise the antenna a bit.

"That's the goal. That's the goal," Wentz said. "But there really is no timetable, no rush. But I feel good with the progression I've been on."

On a cursory level, Wentz looked healthy Monday and claimed that he was feeling good while taking things "week to week." He's already been cleared to throw at least some and run a bit but steered clear of any specifics when it came to recovery.

After having two consecutive seasons shortened by injury the fourth-year pro is aware that the questions surrounding his durability will continue until he proves he can handle the rigors of 16 games again.

“I get it. I get it,” Wentz said of the concerns. “I’m looking forward to putting those behind me. I understand it’s a part of this league, it’s a physical league and things happen. Some of those things are out of my control and I look forward to putting that behind me.”

ADAMS TO MISS TIME AFTER OFFSEASON SHOULDER SURGERY

Second-year running back Josh Adams had offseason shoulder surgery and will miss at least offseason workouts, something first reported by NJ.com and later confirmed by a league source.

An undrafted player out of Notre Dame last season, Adams, 22, slowly worked his way up the depth chart and finished as the Eagles’ leading rusher in 2018.

Adams is expected to be healthy for training camp where he will be welcomed back to a RB room that now includes trade pickup Jordan Howard, as well as the returning Corey Clement, Wendell Smallwood, Boston Scott, and Donnel Pumphrey, along with another back or two from the upcoming 2019 draft class.
